Hi,
I have implemnted basic application named "xyz" in Opendaylight beryliium that receives notification for topology changes.
I have extenal application say "pqr" that does some action if there is change in topology. The application "pqr" is developed using c++. Now I want to send notification from xyz to pqr whenever there is topology change.

I think that can be done using socket or by creating some rest interface between thses two applications.

One option is to use a message passing service. There are some efforts in OpenDaylight to integrate with Apache Kafka, so you could potentially take advantage of that, since Kafka does have C++ bindings.
